"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

There are two main reasons your furnace and AC are turning on at the same time. The first could be that you’re confusing the furnace with the blower. The blower is located in the furnace and will turn on to distribute cool air from the air conditioner through the ductwork in the home. This is normal. If the actual furnace is turning on at the same time as the AC and hot and cool air are coming into the home, it could be a result of incorrect writing to a new thermostat or new systems.

Replacing an HVAC system does not always include new ductwork. The decision depends on the condition of your existing ducts. If they are in good shape, correctly sized for the new unit, and meet current standards, they can often be reused. However, if the ducts are damaged, poorly designed, or improperly sized, they will likely need to be replaced or upgraded to ensure the new system operates efficiently. An HVAC contractor will assess your ductwork and recommend the best course of action. Typically, ductwork is purchased separately, and a full replacement will add to the overall project cost.

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.

Yes, government incentives and programs are available to encourage energy-efficient upgrades in many regions. These incentives may include tax credits, rebates, grants, and low-interest loans for homeowners who invest in energy-efficient improvements such as HVAC system upgrades, insulation, and efficient windows. The availability and specific details of these incentives can vary by location, so check with your local government or utility company to explore your options.

There are several tell-tale signs that your AC coils need cleaning, including:

  • You’re getting higher electricity bills.

  • Your home doesn’t feel as cool as it usually does.

  • Your AC unit is running longer than usual to cool your home.

  • Your home is more humid than usual.

  • The coil is covered in frost while running.
