Recent Review: The tenant at my rental house called to let me know that the furnace seemed to have a gas smell and that it was not lit. So, she turned off the gas. I immediately called Howard Air to come out to inspect. They first told me to contact the gas company since the gas company would come out to inspect right away. The gas company came out immediately since this is considered an emergency and determined that there was a problem with the furnace and that the gas should remain off until fixed. Then, I contacted Howard Air again to come out to inspect. Howard Air informed me that the heat exchanger was cracked, which is dangerous, and that the furnace would need to be replaced. The next day, they sent a salesman to inspect and provide an estimate on replacement. After receiving an estimate, I told the salesman (Brian) that I would need to get a second estimate before agreeing to their proposal. However, after hanging up the phone, I decided to call back to see if they would apply the discount coupon from Angie's list to the purchase and installation of the furnace. Brian was able to contact the office to get agreement to apply the coupon, which is normally applied for a complete system rather than just a furnace. Since, they agreed to apply the coupon, I went with Howard Air. Howard Air arrived to install the furnace the next day. The installation was done in a timely manner, and the tenant was very pleased with the work they did. I was able to see the installation later. It looked well-done. But, there were two joints on the duct work exiting the furnace that did not have the aluminum tape applied as was done for the other duct joints. I asked the salesman why that was not also taped. He said it was not needed. After I requested, he had the installation technician call to explain why, which the technician did. It still seems to me that it should have been done since it is simple enough to do. I may still tape it myself. Brian said that a final invoice would be emailed to me as was done for the proposal. I called a couple of days later to request the invoice from Brian and also sent him a text message on the phone and an email. But, still did not receive a response or the invoice. This is typical of what I have seen with service companies. The response seems generally slower after the sale, which I do not like. I called the office more than a week later, and they emailed the final invoice that day, I marked this review that I would use Howard Air again since there is not a choice to say I'm not sure. Overall, I think I would use them again. But, due to the response of getting my invoice after service, I would definitely also consider other companies in the future.
