"I really can't say enough good about Westin Air and the team of people who work there. Professional all the way. This was simply an annual system check-up on the TRANE HVAC system Westin Air installed late summer last year. Justin and Frank were the technicians. They neatly performed annual maintenance on the system and answered a few questions I had about the unit's staging system. These folks are PROS and I highly recommend them."

"We were very pleased with the service that we received from CARE! I contacted three different companies and they were the first to respond and their estimate was the cheapest. We were looking for a basic system and that is exactly what we got. We did not feel pressured to get anything more than we asked for and Andy was very helpful. Matt and Kirk, who installed our new system, were fast and efficient. We will definitely contact CARE again in the future for any HVAC needs."

"We had a great experience with Franklin Heating/Cooling and their employee Tony when they came to fix our AC. From start to finish, Tony was professional, efficient, and incredibly honest. It's not every day you come across a service company that doesn't try to upsell unnecessary repairs or replacements. They took the time to thoroughly assess the issue, explain what needed fixing, and offered a clear, fair solution. We really appreciated his transparency and how he genuinely prioritized our best interest over making a quick sale. It's rare to find companies that are this trustworthy, and I will definitely be using them for any future HVAC needs. Highly recommend!"

"Tyler replaced our 22 year old central air conditioner. From the initial call for a quote to the final installation the entire project was perfect. His years of experience were obvious as the job was professionally handled. He later serviced our gas furnace, explaining all of what was occurring while giving the furnace its best check ever. Delta-T is our "go-to" HVAC firm in the future."

Heating and Air Conditioning questions, answered by experts

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

Don’t run your AC with a wet filter. It can cause your AC to work too hard, which will run up your utility bill and cause extra wear and tear on the system. You could also spread moisture and mold throughout your house. Turn off the AC, remove the wet filter, and check for cracks or clogs. Fix the problem (with a pro’s help, if you need it), and put a dry filter in place before you turn the system back on.

If left untreated, a frozen AC unit can lead to costly damage, especially to the compressor and evaporator coils. When ice forms on the evaporator coils, they become brittle and more susceptible to breaking. Plus, a freeze makes your AC system much less efficient, which means it's wasting energy and costing you more in your monthly energy bills.

If both your furnace and AC unit are more than a decade old, it may be a good idea to replace both of them. However, your furnace can last up to three decades, and your air conditioner can typically last up to 15 years, so consulting with a pro before deciding to replace both of them is best. If it’s before that time limit for each, you can fix many problems with repairs or just replace one.
