"Recommended various expensive measures that were not necessary (including buying new AC unit). Had another company come out and they addressed the problem while" recommending a solution that cost a fraction of the proposal by
& Sons. Would not recommend them.

"My house was struck by lightning, with a gas line running to my heater actually catching on fire, resulting in the fire department coming out. The gas line was damaged" and needed to be replaced.
and Air was in the neighborhood and advertised heavily on local media about how well they would take care of me. When I went to the office to make an appointment, I was told they were too busy handling air conditioning calls to worry about my damaged heater line. However, I they did make a ticket and told me it would be about two weeks before they could get to it. That's the last I ever heard from them. I find it incredibly unprofessional for them to actually fill out a work order ticket and never follow up on it. They are clearly not interested in my business, which I was happy to take elsewhere. I would not reccomend this company.

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.

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.

I thought I had a freon leak. The AC unit was turning off and giving an error code. I had this issue when I first srt it up (DIY,). I had calleded a small local AC guy I found on Angies List o fill it, seal it and check the pressure. I had him come back two more times when I had problems with the unit. He didn't know anything about mini splits and could not figure out what was wrong. It is quite possible what he did damaged the unit (though it could also be factory defect). Regardless, I found Fly onot Angie a List. Lots of reviews, very low negative rate, professional, informative responses, local business a good size but clearly home grown in Houston.

When I called, I mentioned the type of unit I had. The woman who answered put me on hold to see if either of the only two people on their staff experienced with mini splits was available. It was 102? outside, they were slammed and we had no AC.

came out that very day, asked questions, and got on the phone with Fujitsu tech support. Had the problem diagnosed in a few minutes, ordered the parts, and offered not to charge for the visit. I paid him anyway and he applied it toward my next call, which came a week or so later when the part came in.

was one of 2 HVAC companies that we asked to come and evaluate an on going issue we were having with the Heat Pump systems in our home. These systems, 3 of them, were all approximately 20 years old. Both companies quickly identified major issues with two of the systems, and minor issues with the third. Given the age, both recommended consideration be given to replacing the systems; however,

was the only one that offered to repair the systems however they very clearly stated that the cost to repair could easily exceed a reasonable amount, and could offer no assurances that something else wouldn't fail with these units. I asked

I purchased the special offer of 79 $ for air condition check up. I just bought the house and the air condition made weird noises. I chose this company to perform maintenance on the system and they came on time.

Our heat pump just wasn't cooling the house in the 90+ degree weather we were having. I noticed ice on the inside coils. I called the installer,
Rockville HVAC Contractors Provider Name Locked
& HVAC. They went out of their way to schedule to get us a technician to look at it the same day. My wife had just had surgery & my 87 year old Mother-in-law lived with us so I wanted it fixed fast. The technician found a coolant leak and when he touched the fitting it broke and filled my basemen with coolant. The technician went into high gear to help me clear the gas out of the basement & find me a replacement part. The only coils he could find were in Allentown (75 miles) and couldn't be delivered till Friday afternoon. That particular technician had a full schedule on Friday & was leaving for vacation Saturday. No one else was available until sometime next week. I said what if I drove to Allentown & picked up the part. He said that if I was willing to do that he would come back on his own that evening and install it. In addition he would come over the next morning before his regular shift to charge it. So I tool off for Allentown and true to his word, when I got back he came over & installed it. At 6:30 the next morning he showed up to recharge the unit.
This is the kind of service I have received in the past from
