"WARNING - make sure you get a fully price estimate up front before they begin to do work. I brought them in to work on furnace/AC unit/split AC unit servicing garage (based on a promotional price for the first two). It was found my split unit needed a recharge for coolant and I was told that it'd only be 5 lbs of coolant and that this would be priced by the pound (which was reasonable). The bill came and they tacked on a flat charge of $219 for the coolant (this is in addition to the $129 charge to look over the split unit). I felt baited-and-switched. I also contacted them about this, and the answer came down to "This is additional profit for us added onto your bill." Not pleased. At all. Particularly since the coolant in question costs approximately $6 per pound and they only used 5 lbs (one would assume that the $129 charge built in enough profit for labor/licenses/equipment due to the limited time spent working on the split unit. Apparently not). Comfort By Design does excellent work, and they do stand by their work, but just be VERY CAREFUL in finding out what they're going to charge you, particularly if something extra comes up when they're doing a job."

Phil at Angell Aire provided the information we needed without a high-pressure sales approach and offered the best price (by far). The installation was done in a 1/2 day and and the quality of work was exceptional. The whole process was short and easy and without any hassles. I would definitely recommend Angell Aire to anyone."

"My chest freezer broke down and I did not want to buy a new one since I could not afford the same size. I reached out to appliance parts pro and they were confident that what I ordered would fix my problem. $200 in parts later and I now have a broken freezer on my porch and am still paying the loan to this terrible company. They just want you to order parts and try them because they know you can't return them. I hate this company with every fiber of my being and will make sure that anyone that has a broken appliance will not use them. To top it off, their site is so screwed up that it give you an error trying to log back in. I ended up having to create THREE different accounts because every time I went to place a new order, it would not let me login and it would not send a password reset email. DON'T GET RIPPED OFF."

Family owned and operated since 1976, LaMettry's grew from a single location in the family garage to the 10 location business it is today. We are a leader in the industry with many auto manufacturer collision repair certifications.

"Fantastic all around. My car was such a sorry mess and was in the cusp of needing to be totaled due to engine area damage especially. Everyone there in Richfield was top notch in customer care: Sheila, intake at the front desk; Greg the lead estimator; Mike who updated me w/details twice a week over the three week period; and Venisha who worked with me when I picked up my car, were welcoming, pleasant, compassionate, and absolutely consummate professionals. Especial shout out to Greg, who worked with all the staff there to look for my key ring I thought was there; he was so helpful....and it turned out my ring was in a purse at home that I hadn’t at all remembered putting there. Additional point on that is that throughout my entire process, each Lamettry person seemed to really understand—through their professional & kind demeanor—the traumatic car crash experience that their customers like me have just experienced. And then I find out today the Lamettry Values and Community Service that’s expressed on their website. They really do walk their talk. Highest Kudos to every person there. And my car? Absolutely fantastic work. Beautifully done. I give my highest recommendation to use their services. Lor L."

Heating and Air Conditioning questions, answered by experts

You need to know the square footage of your home first. Multiply that number by 20, which will get you the BTUs (British Thermal Units) needed to cool your home efficiently. Homes up to 1,000 square feet usually need a 1.5-ton unit; homes 1,000 to 1,200 square feet usually need a 1.75-ton unit, and homes 1,200 to 1,400 square feet usually need a 1.9-ton unit. Talk to a local pro for more specific advice on your home. 

There are many signs of a bad AC fan motor, including if the fan blades don’t spin when the AC kicks on or if they keep spinning when the AC is off. The AC fan cools down the condenser coil, so a faulty motor can also cause the system to overheat. Unusual noises in the exterior AC unit, including grinding or rattling sounds, may also be a sign that the AC fan motor is worn out.

Running a window air conditioner unit costs about $0.06 to $0.88 per hour. Choosing the correct size air conditioner can help it run more efficiently.

Many factors affect how much adding air conditioning will cost you, from the size of your home to the size, type, brand, and installation specifics of the system itself. Chances are, a new central air conditioning system for a 2,000-square-foot house will cost somewhere between $3,900 and $7,900 to install, with an average around $6,000

To find a reputable HVAC company, start by finding providers in your area that have mostly positive reviews online. Next, check the Better Business Bureau’s website for customer complaints. Some states and municipalities require technicians to be licensed, so you should rule out companies that aren’t. Finally, contact each professional and ask for per-hour pricing, contract availability, and references to call. You can also ask if they have worked on your particular system brand in the past to confirm that they’re qualified.
