"Prompt response. Had to move the original appointment, but was prompt, courteous and professional. Cost much more than the Angie's List special rate due to other issues.

"We have used this company before, and, as always, we were very pleased with his promptness to come (hot summer days; air conditioner not cooling as well). He explained" to us that as hot as it was, we needed to limit going in and out as much as possible because it pushes the air conditioner, etc. No one had ever explained this to us. He put Freon and checked other parts of the air conditioner to make sure everything was working. He does great work, but he wants to save the customer money by giving them tips. We think he is reasonable, as well.

Hiring an HVAC service

The awkward-to-pronounce acronym stands for "heating, ventilation and air conditioning" which in many respects are completely different processes.

HVAC Maintenance

You can help your heating and cooling systems work more efficiently and last longer by tending to regular maintenance. Some things, like changing the furnace filter, can easily be done by the homeowner.

Radiant floor heating is arguably the ideal home heating system. It’s comfortable, efficient, unobtrusive and quiet.

what should you pay.  You pay what you can afford.  1100sqft unit requires a min. of a two ton unit.  prices range from 2100-2900 depending upon the seers of the system.  13 seer is the min. the law requires  and for your situation with 1100 sqft.  do not worry about the seers as long as it is to code.  the bigger the house the more seers for economy.  1100 sqft is at the border line for a two ton system.  It is more important to have your new system balance, there is where you get the economy on your electric bill and gas.  Bryant, lenox, ruud and carrier are the brands you should stay with.All have the same basic factory warrantee and will last you longer than you expect as long as you maintain it with regular check ups twice a year once in the spring and then in the fall.

The only thing of importance, is the hvac professional you choose to use. Alot of manufacturer's pieces are built relatively the same, and will last about the same amount of time. The thing that matters most is what you can not compare between companies, and that is the installation. Purchasing a system is not like purchasing a car, where no matter where you buy it, they are all the same. Each installation is different, and usually what you are paying for is the level of expertise, and quality of the installation, the company who will actual give you the warranty, and the comfort that you will receive. Manufacturers warranties disappear every day. They always have a loophole where they can get out of paying, but your local dealer wants to keep you happy for future work, and to protect his reputation in the communiy. Look up 4 year old Nordyne and Goodman warranty problems. Choose the HVAC professional first. It will cost you the least in the long run. I have had to totally redo plenty of installations that were just performed because of an uncomfortable customer, and a system that keeps breaking down. The equipment is only as good as it's installation, and over 70% are not installed correctly.

Yes Jupiter. It depends on the severity of the situation, is the mold encapsulated in the insulation. If yes, than replace [insulation] it with new. Is it on the casing of the heater? If yes, clean it with a mold neutralizing metal cleaner. It's not a matter of finding something or someone to clean or address the existing mold. It's a matter of finding a contractor to rectify what is causing the mold grow. It's coming from excessive moisture in the air-handler unit. I can say with 100% surety you’re dealing with poor airflow and/or incorrect equipment sizing! Either issue will cause excessive icing of the evaporator coil, which leads to excessive condensate water in the system. The condensate will eventually overflow the drain pan leaving stagnant water in the air-handler housing, which leads to mold growth. I would not let any contractor do any kind of temporary repair, add any device like a UV light or air-cleaning product until the aforementioned is corrected. I talk a lot about this in my videos and on my website. It is the result of improper system design from unqualified contractors. There is a reason why some guys cost more than others, and this is one reason why!

I'd rate them equal,or close,as with several other brands. I'd be more concerned about the difference in installation and service down the road. Difficult to determine the difference ,but asking for detailed info about their installation,may convince you to choose one over the other.

The Dept. of Energy states that poor installations can cause a 30% efficiency loss! Plus with Gas their are saftey issues,venting properly etc.,and of couse the need for a "low Level" Carbon Monoxide Alarm.

I think maybe you are confusing SEER, which is an efficiency-related rating (higher SEER means more effective use of the electric power used to compress the gas), and TONS rating, which is a measure of the total cooling power of the system. (Tons used to mean how many tons per hour of ice was used in evaporative cooling building systems - a Refrigeration or Cooling Ton equals 12,000 Btu/Hour of energy exchange. A BTU, which is another antique measure but still used, is the energy needed to change the temperature of a pound of water one degree fahrenheit. Unfortunately, because of varying humidity and evaporation, this is not readily related to house air heating or cooling without a lot of assumptions and some computations. Relating this to today's world - the Manuals BayAreaAc referred to account for all these energy conversions and determine an estimated cooling (or heating) requirement for your specific house. The type of construction, solar exposure, general climatic conditions such as average temperatures, humidity, and hottest and coldest normal ambient temperatures and desired inside temperture are all taken into account in the more sophisticated versions of the analysis, so there is no "standard", though a rough old rule of thumb was about 1 ton of cooling per 500SF of house. Obviously, this was a WAG only because it did not account for insulation, type of roofing, whether you live in Alaska or Miami, etc. The ACCA manuals do a very simplified form of evaluation to arrive at a "design", which generally will be adequate. OF course, highly precise calculations are not really needed because A/C units generally come in even ton ratings - so if you are at say 2.6 ton requirement you will be getting a 3-ton unit anyway. SEER ratings are not a direct measure of efficiency, but the relative difference between ratings gives you good idea of the unit's relative efficency in using electricity - so a 16 SEER should be about 19% more efficient (so roughly comparable lower electricity bill) than a comparably sized 13 SEER unit. 13 SEER is the lowest efficiency currently allowed to be built for general use, 19 SEER is about the highest efficiency made by pretty much all manufacturers, and about 25 SEER is the highest rated though very pricey shelf-item units, though special construction custom units can reach about 30 SEER. Note however, like any government sponsored rating, much of it is hooey when you get down to it - for instance, SEER ratings are figured based on 80 degree inside air temp and 82 degrees outside, when that is far from the normal case of mid to low seventies inside and high eighties or above outdoors. This makes the absolute SEER rating meaningless, but relative numbers still have meaning in comparing units. Note these efficiency ratings are for conventional air conditoners and heat pumps working in ambient air conditions. Ground sourced Geothermal or lake/river exchange cooling units, though initially more expensive in most cases, can greatly exceed the air-exchange unit efficiencies because they are exchanging heat with cold natural water rather than with a high-temperature outside air, and instead of continually compressing a gas are just circulating cold water. I worked on one geothermal cooling project which had almost infinite efficiency, which of course makes no sense - but the only power was for sensors and a control valve as the water flow was single-pass under gravity flow, so no power was used to circulate the water.

Just purchased a dual voltage capacitor at Home Depot for $8.34 and it literally takes 5 minutes to remove and replace. Make sure to shut the power (pull the fuse), short ALL connection points on the capacitor and do it yourself. If anyone tries to charge you more than $150 total (for labor and parts) please chase them off your property.

Our HVAC system is almost 20 years old and is showing its age. So we decided to replace it this year. We called three providers (all ranked A in Angies list) for an estimate. Among them, the representative from Signature did the most through job of explaining to me all the different options available and all the little extras that we will get for using their installation. And they also offer the best price for the package that we picked.
After signing with them, scheduling the actual installation is a breeze. They are able to do the installation in just couple days. The installation team arrived early in the morning and get straight to work. They are very professional, polite and efficient. Everything was done by 4 pm. The system runs beautifully and we are confident that it will provide the comfort that we need for years.
I will definitely use Signature for all my HVAC needs in the future.

Let me simply say, of all the companies I have ever hired and/or worked with as a homeowner, this company stands out as the least professional and most frustrating. I would never recommend them to anyone else. If my husband didn't have some background in HVAC, we would have absolutely had the wool pulled over our eyes by this company.
Called mid-June, and was told work would be done in
Duluth HVAC Contractors Provider Name Locked
...when explained that I was 8 months pregnant, they did bump me up to June. That was the ONLY plus. It gave me hope this was a decent and helpful company looking to please their customers.
Promised a one day job, "no matter what" because they had other jobs to get to. Showed up on time the first day, left hours early with job not even close to done.
Showed up three hours late the second day, two hours late the third day. Both days no call to say they'd be late until I called them several times.
Sent a total of 5 different workers from different departments in the business over a 5 day span who all then had to guess at what the others before them had or had not done. My husband spent many hours assisting them because they only sent one man when told they would send two. I can't understand why you wouldn't just finish one job and move on to the next rather than continuing to split men up and cover everywhere/leave commitments unfulfilled.
It took them over seven weeks to fully complete the job, as other issues arose as they worked. We had to hound them to come back and fix issues.
The communication between departments, employees and customers leaves much to be desired.
On top of all this, the people who work in the office are rude and snarky.
I cannot express my disappointment enough.

The electrician was very helpful and completed the requested services. The services were purchased through Angies List. The provider contacted me that day to schedule the service. The electrician was punctual and professional.

The home warranty people sent them to my home because my downstairs unit is working inconsistently. He went into the attic with no tools or gauges, not even a flashlight. Looked at my unit and said I would have to pay him $1200 to clean the coils in the attic before he could tell what was wrong with the unit. The coils are not visible because it is a closed unit. He said they should be cleaned once a year. I told him it was ridiculous that I would be expected to pay $1200 annually to clean a unit that could be replaced for @ $2400. I asked him if he would add some Freon to the unit, and he said he couldn't do that without first cleaning the coils. We had a reputable company come out in June to inspect and clean both our units and they were fine at that time. So, now my battle is with the home warranty company that uses this scam of a a/c company.

After installing a $8000 complete A/C System 4 years ago and a $300 UV light a couple years ago, I called them to request a service call to fix the A/C system and they said they do not service Lakeland, FL anymore. So much for 45 years serving customer. I wasn't aware of their Bait & Switch program when I purchased their products and services.

Although he did do the refil he was hard to reach and slow to respond. For a unknown reason he failed to return my call and after a week I left another message. He didn't respond to me but texted my wife and referred to her as beautiful lady. He then over many text made it clear that he disagreed with our marriage and wouldn't provide services . He went on to claim many things such as my wife's husband that died when they were married was a lier, along with several false and degrading things about my wife and I. He also discussed our finantial condition with facts that weren't at all correct. We both were very confused by what was being said and offered to discuss everything It ended with a rant to basically call me out to a confrontation. I believe

We had our central heating and air replaced about 16 months ago and it has gone out twice already for a total of about 2.5 weeks without A/C during the middle of the summer. They recommended using incompatible units inside and outside to "save on energy costs." WRONG! They did an awful wiring job that I had to inform them was not even up to code. SERIOUSLY!? Terrible service. I do not recommend using this company!
